When entertaining friends, family and neighbors, you want your deck to look its best. Drifting embers from a grill or fire pit cause burn marks on the wood that detract from the visual appeal. Burn stains leave the surface looking unkempt and dirty. Strategically positioning a piece of furniture, plant or small rug only hides the stains. Repairing the burn marks is a permanent solution that will keep your deck looking neat and tidy.

Save money by repairing wood decks yourself.

Surface Burn Stains

Step 1

Sweep the deck with a push broom to remove the dirt.

Step 2

Mix a 1 teaspoon of grease-fighting liquid dish soap with 1 gallon of water in a bucket. Wet the deck with the spray from a garden hose. Submerge a stiff-bristled scrub brush into the soapy water and scrub the stained area of the deck. Rinse the deck with water and let it dry.

Step 3

Cover a sanding block or an orbital sander with 120-grit sandpaper. Sand the burn stain on the deck following the grain of the wood until the burn mark disappears.

Step 4

Sweep the sanding dust with a small broom and collect the debris in a dustpan.

Step 5

Paint on a coat of penetrating sealer to the repaired section with a paintbrush if the rest of the deck has a coating of sealer.

Deep Burns

Step 6

Sweep the deck with a broom.

Step 7

Wash the deck with grease-fighting dish soap and water. Rinse the soap residue off the deck with water and let the deck dry.

Step 8

Hold a butt chisel at a low angle to the burn stain with the cutting end facing the stain. Lightly tap the handle of the butt chisel with a mallet or tap it with the heel of your hand to shave the stain out. Continue to chisel the burnt wood until you reach bare wood.

Step 9

Dip a paintbrush into penetrating wood sealer and apply a coat over the chipped-out area. Let the wood sealer dry for about six hours.

Step 10

Mix two-part epoxy putty, according to the putty manufacturer's directions. Scoop up repair putty on a putty knife and press it forcefully into the chipped-out wood until the putty is flush with the surrounding deck. Let the repair putty dry for about six hours. Cover a sanding block with 120-grit sandpaper and sand the putty surface smooth. Apply penetrating wood sealer around the repair.
